mtest: TestResult.SKIP is not a failure (#7525)

* mtest: TestResult.SKIP is not a failure

If some but not all tests in a run were skipped, then the overall result
is given by whether there were any failures among the non-skipped tests.

Resolves: https://github.com/mesonbuild/meson/issues/7515

* Add test-cases for partially skipped TAP tests

issue7515.txt is the output of one of the real TAP tests in gjs, which
failed as a result of #7515. The version inline in meson.build is
a minimal reproducer.
